AFAIK, there are no neutered professions in German. So that would be a big change, it's hard to imagine.

I know very little French, but if I understand correctly, because person in French is female (la personne), you could have a sentence mentioning "the persons" (plural) (les personnes?), and then later on using the pronoun "elles" (female version of "they") to refer to them. So a female-coded pronoun would refer to a mixed-gender group of people.
